SUSPENSION-INSULATOR.

and. more particularly to an insulating means comprising a. plurality of concateseparately formed insulating parts connected in series, .sa'idparts being flexibly joined together and the several units being suspended from one another in column adapted to support a conductor from .the lowestunit in the column, the arrangement being such as to securea large insulating value especially for resisting charges oflightning or the like, and without the necessity for handling largeindividual insulators.

Among the more important objects of the invention may be enumerated the following; I. To connect together a plurality-of insula-' tor units in. concatenated relation, and to form said units of parts so formed and disposed as to minimize the likelihood of the formation of conductive paths between the several units of the concatenated structure, which paths are ordinarily caused by dripping, or running, of water from one unit to the next below, or by the' formation of icicles extending from one unit to another. II. To form an insulator unit for use in a concatenated structure, the unit comprising a part of relativelv great vertical length depending from a part of relatively less vertical length but relatively greater horizontal dimension, the latter forming a water shed for the former, and the forming serving to space the water shed a considerable distance frpni the Water shed of the next unit below in the column, so as to materially minimize the likelihood of the formation of conductive paths between said units as above set forth. III. To provide an insulator unit for use in a concatenated structure, the unit comprising a plurality of insulating parts arranged in series, and to provide a protective member for protecting each of said insulating parts in'common. IV. To provide ,"an insulator unit for use in forming a concatenated structure, the unit comprising an insulating part disposed horizontally, and "a second insulating part disposed vertically Specification of Letters Patent.

and pendent beneath the horizontally disposed insulatlng part connected in series, and to prov de a protective member directly above the horizontally disposed insulating part adapted for protecting both of said insulating parts against theelements.

Other objects and aims 'of the invention, more or less specific than thosereferred to above, will be in'part obvious and in partpointedloutin the course of the following description of the elements, combinations, arrangements of parts and applications of principles, constituting the invention; and the scope of protection contemplated will be indicated in the appended claims.

In the accompanying drawings which are to be taken as a part of this specification,

and'in which I have shown a merely preferredform of embodiment of the invention:

'Figure l is an elevational view illustrating a concatenated series of insulating units con- 'structed and arranged in accordance with the provisions of thisinvention, and having a conductor supported thereby; and Fig. 2 is a top plan view of one-of the insulator units,

IIII of Fig. 1.

indicate, generally, two of the units form ing' the basis of this invention, said units be ing directly supported by a suitable insulator unit 3 from any form of support (not shown) through the medium of the eye 4 in the upper end of the insulator 3. It will be understood that there may be as many of the units 1 and 2, as may be, desired in any concatenated structure, and that each of said units is substantially identical in formation, so that a description of one will apply equally to all. Each of the units comprises a rod type insulating part 5 disposed horizontally, and a similar rod typeinsulating part-6 disposed vertically. The insulating part5 is directly supported from the end ortions 7 of a bail 8, which spans above the insulating part5 and is formed with opposing parallel portions 9 between which is supported a protective member 10 in 'position for preventing direct access of rain water and the like to the insulating parts 5 and 6 therebeneath, the protective member comprising'a wide flaring flange for that urpose.

is formed, intermediate its length, with a lug 11 providing means for said view being taken on the plane of-line cally beneath another similar unit, then to the similarly bifurcated end 13 of thevertidisposed insulating part 6 of said unit next above. The insulating member 6 is provided, at itsupper end, with a metallic/ ters Patent, is:

band 14: arranged to encircle the insulating member 5 intermediate the ends thereof, in such manner that the insulating member 6' depends vertically centrally beneath the; insulating member 5. The protective member 10, above the insulating member 5, is of such proportions as clearly'indicated, e'spe 2,-t0 form an *efiicient protection not only for the member 5, but also for the member 6. Though, only one of the vertical insulating members 6 are shown, it is apparent that if desired, others may be arranged parallel with that illustrated and be connected with the member 5 nearer its ends in like'manner as is the member 6 at the middle of the member 5. j I

a The numeral 15 indicates the supported conductor provided .with 'a clamp' member 16 connected by bolt 17 to the lower end of the lowest vertically disposed insulating part 6 in thev concatenated structure. It will be seen that a chargeof current from the conductor 15, encountering the first insulating member 6, if of Sufiicientstrength to bridge or pass throughsaid' insulating member, must encounter the first insulating member 5 and bridge or pass through it before being able to reach the parts of the next unit above and so on, in series, through the structure to the common supcially in Fig.

port thereof: It is thus seen that though each of the insulator units comprises separately formed part-s connected in series to provide desired eihclency, the single protcctive member 10 of each unitamply pro-- tects the individuaLparts of the unit and avoids the necessity for a separate protective member for each of the insulating parts. Consideii-ble expense in manufacture, and difiicult-y and expense in handling, is avoided, and thegeneral'appearance of the structure is improved without detracting from the dielectric walues of the several parts. I

As minor changes could be made in the above construction without departing from the scope of the invention, it is intended that all matter contained in the above description or shown in the accompanying drawing shall be interpreted as illustrative and not in a limiting sense. It is also to be understood that the'languageused in the following claims is intended to cover all {of the generic and specific features of the invention herein described, and tocover all variations of the invention which might be 'said"to fall-within the scope-of said lan- .4 I,

Having thus described my invention, .what I claim as new and desire to secure by Let- 1. A suspension insulator comprising a plurality of. separately formed units arranged in eoncatenated'relation and adapted to support a conductor. vfrom the lowestnnit in the column, said unitsbeing' alternately horizontally and vertically disposed, and
